NOTES:
1. Mounted on 5.0mm (.013mm thick) land areas.
2. Measured on 8.3ms, single half sine-wave or equivalent square wave, duty cycle = 4 pulses
per minute maximum.
3. ZENER VOLTAGE (Vz) MEASUREMENT Nominal zener voltage is measured with the device
function in thermal equilibrium with ambient temperature at 25
